Hi, I am trying to create a Tweet rotator using AngularJS and JQUERY but I am getting the following error:
XMLHttpRequest cannot load https://api.twitter.com/1.1/statuses/user_timeline.json. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin XXX is therefore not allowed access. The response had HTTP status code 400.

The Twitter API does not return a Access-Control-Allow-Origin header, so it is not possible to request it directly from JavaScript using Ajax or similar. You need to have a backend, that kind of ‘proxies’ the requests to the API or so, in order to do so.
